Although the service is fantastic I have found the products to have an after taste. This is really hampering my ability to go forward with this product which otherwise I love. It has helped my nails for sure but so far after trying a month of the unflavoured Marine collagen and a box of the samples (I only kinda liked the Coconut creamer from that boxand the cinnamon flavour was not in there) I am not seeing any real change in my skin. So although I love Dose and Co I do wish this background taste could be removed. I am going to try a month of the coconut creamer and if I still feel the same after trying that I will have to try another product :(. A shame because SUCH good service. If you don't get the after tase as I do then this is a fabulous company to get your collagen from.
